Re: Mach2 Unguided imaging results from last night

I suspect that the answer would depend on the focal length or pixel scale that you are imaging at.

Rolando, any suggestions on how many data points (in general) should be enough with APPM?

If the object is on Dec 60, then opposing dec lines would be 50 and 70.

However, if you are using APCC Pro (APPM) then just do an automated all-sky model. Doesn't take long.

Sorry ... I pushed Reply before typing out my question for Roland and/or other unguided imagers:

Given Roland's scenario of M52/Bubble, these "opposing Dec lines" would be what exactly?

I'm looking to replicate your quick point data modelling for my non-permanent 1100GTOAE setup with APCC/APPM.

I took quick pointing data of 5 stars each on opposing Dec lines instead of taking data along the object's path. This way the modeling program could better calculate orthogonal errors, polar alignment error, scope flexure, as well as the drift error due to atmospheric refraction.

1600GTO RA Worm damage?

Mike Shade
 

A couple of questions...in PemPro, what would a damaged first generation 1600GTO RA worm look like, in the data?  Is there a way to tell?

 

If it is suspected that the worm is damaged, is there a solution?  I would really like to replace with the newest "self adjusting" gearboxes, is this possible, regardless of potential damage?

 

Greasing with scope pointed north over mount, some wind and a inattentive helper...not a good day.

Yes, you need to be connected to the mount for the AE tab to appear.

Re: New Mach2 Problem

Ray Gralak
 

Hi Roland/Larry,

I powered up my Mach2 last night for the first time and connected it to latest APCC and V2 driver.
It goes to all of the park positions fine except Home.
On APCC's "Park" tab, parking to the Home position was trying to use the mount's internal, non-encoder home position, and not the Mach2's hardware home command.

This will be fixed in the next build of APCC Pro, which should be v1.8.8.1. (It's not available yet, so don't look for it.)

For now, if you want the Mach2 to go to the home position, use the "Find Home" button on the "AE" tab in APCC.

$HA# is the fundamental command to send the Mach2 home and do a recal. It is the command that would be sent by
any app that knows how to communicate with the mount. The latest version of APCC Pro sends this command when
you press the HOME button. If all else fails, you can input this command yourself and send the mount home, recover
the proper alignment and thus recover from an errant sync.

couldn't find any reference to "$HA#".

Is it discussed in the manuals?

Thanks for all of the great information Robert.  I will check it out.

I have a couple of opportunities for ISS next week where it gets as high as 45 degrees so I am going to try and get a video if I can.

Re: Recommendation for CP4 firmware update for remote telescopes

Robert Berta
 

I would not try doing this with every thing connected. Sounds like a recipe for disaster for a remote setup (although Roland might put me at ease). 
Reminds me of the story about a new computer design. It can talk via AI and it says...."This is the latest version of our operating system. We have spent millions developing it for ease of use so  enjoy it. We know it will meet all your needs and be trouble free as nothing can go wrong.....go wrong...go wrong....go wrong......."


Re: Satellite Tracking

Robert Berta
 

Try the SATELLITE TRACKER PROGRAM....I think it is still free and available having been "resurrected" recently.  I have used it for years with my old Celestron GPS 11" fork mount telescope. I have also use it a couple of times with my AP 900 and 1100 mounts. You have to select Meade LX200 interface in the software as AP also has that option. If you get the program go to the helpfile...it discusses this.There is another app called SKY TRAC that does the same thing. I have that also but thus far having tested it against the older SATELLITE TRACKER program. It does use ASCOM so might be better choice for AP mounts. 
That being said I prefer using the Celestron as it is a bit easier to setup and very accurate tracking as ALT/AZ mount has an advantage in this application.  To use the program you have to have a mount that can be set (from the app) to different rates on each axis and at the same time. The Celestron can do it and from my preliminary tests it seems the AP mounts can also. Some mounts (like the original LX200 will move jerkily in the tracking but Celestrons are smooth. 
I once setup my Celestron's at a star party and people mobbed my telescope to see it work. It would make a great Outreach tool when equipped with a video camera outputting to a TV monitor. The program has built in all you need to download latest TLEs each day (best to get latest downloads for accuracy) for things like the 100 brightest satellites which includes ISS. 

The process is pretty automated. You download the TLE, choose which one you want to track and it will alert you when coming into view. It will than fast slew to catch it and than track it.

It is pretty neat to track those satellites in real time. You lock on to the satellite and   the stars move in and out of your FOV as it tracks the satellite. The time must be set accurately of course but it does have a option to  move around a small amount to allow for more centering of the satellite and than you lock in that corrected aim point.
I haven't used it that much lately....interests change....but it is a fun thing to do. Sadly, while I am  mainly into astrophotography, I never took pictures with my setup. Some have and gotten some amazing photos of events like when the ISS and shuttle were docked. Also a photo of the ISS passing across the moon.
